Abstract
A fingerprint identification device includes a first dielectric layer, a fingerprint sensing chip, a packaging layer, a first redistribution layer, a second dielectric layer, a second redistribution layer, and a third dielectric layer. The fingerprint sensing chip is disposed on the first dielectric layer and has a sensing transmission pad. The packaging layer defines a first via hole and covers the first dielectric layer and fingerprint sensing chip. Disposed on the packaging layer, the first redistribution layer contacts a drive transmission pad via the first via hole. The second dielectric layer defines a second via hole and covers the packaging layer and the first redistribution layer. Disposed on the second dielectric layer, the second redistribution layer defines a looped pattern, in addition to connect electrically with the first redistribution layer via the second via hole. The third dielectric layer covers the second dielectric layer and second redistribution layer.
